BAUSCH, Oils BDCHESTEB, NEW YORK, ASSIGNOB TO BAUSCH LOKB OPTICAL COMPANY, 01 RDCHESTR, NEW YORK, A CORPORATION OF NEW YORK TELESCOPI G GOGGLES Application filed November This invention relates to optical devices and more particularly it has reference to telescopic goggles comprising telescope units mounted in a goggle frame whereby the wearer is selectively provided with vision through the telescope units or through the goggle lenses. In the pursuits of aviation, it is generally very necessary for the aviators to wear-goggles to protect their eyes from strong winds,

' directly in front of him.

One of the objects of my invention is to provide an improved and efliclent device of the character described which will afford thewearer either telescopic vision or vision throu h goggle lenses. Another object is to provi e means whereby a commercial type goggle can be readily converted into telescopic goggles. A further object is to provide improved means for mounting a telescope device in a goggle frame. These and other objects and advantages reside in certaln novel features of construction, arrangement and combination of parts as will hereinafter be more fully described and pointed out in the appended claims.

Referring to the drawing:

6, 1929. Serial No. 405,173.

A preferred embodiment of my invention is illustrated in the drawing wherein 10 indicates, generally, a pair of goggles of the type used by aviators, autoists and the like. This goggle has two eye units each comprising a substantially oval-shaped, split frame member 11 having adjacent ends 12 and 12 which are vheldin secured. position by means of a suitable latch 13. The two eye unitsare held 'togethei-iby means of a suitable bridge 14 and each frame member 11 carries a sponge rubber cushion 15. v

The frame member 11 is provided with a grooved portion 16 in which is mgunted the oval shaped support member 17 shown in Fig. 4. The support member 17 comprises three rim portions 18. 1.9 and 20 which are secured, as by soldering, for example, to a plate 21 having an aperture 22. The rim portions 18, 19 and 20 have inner grooves in which is mounted the lens 23, which, of course, is cutaway to provide for the plate member 21 as shown in Fig. 1.

- A pair of smallfield glasses of a Well known commercial type, indicated generally at 24. is mounted with its two eye piece tubes 25 projecting through the apertures 22, the tubes being cletachablysecured to plate 21 by means of the threaded eye caps 26 which abut against the plates 21 adjacent the apertures 22. Slidably mounted on the tubes 25 are the tubes 27 which may be moved axially, for focusing purposes, by means of the screw 28. as is usual in glasses of this type. The two lens elements 29 and 30, forming a telescope of the Galilean type. are carried, respectively. bv tubes 25 and 27.

It will be evident from the foregoing description that. I am able to provide a pair of telescopic goggles which will selectively afford to the wearer either telescopic vision or vision through goggle lenses. It will be noted from Figs. 1 and 4 that the lens 23 extends laterally of and beneath the plate 21 thereby enabling the wearer to road maps or data which are directly in front of him. Since a commercial type goggle frame is used, the telescopic goggles can be readily modified to use regular, full view goggle lenses by merely removing the support members 17 carrying the lenses 23 and the plates 21 which support the field glass 24. The field glass 24 can, moreover, be easily detached rom the plates 21 merely by unscrewing the eye caps 26, thereby permitting one to use the field glass in the usual manner. It will also be noted from the description that the weight of the field glass 24 is carried by the metal lates 21 which in turn are supported in the rames 11. This is an important feature of construction because the Weight of the field glass is carried by metallic members so that lenses 23 are not subjected to undue strains.

Various modifications can obviously be made without departing from the spirit of the invention as pointed out in the appended claims.

I claim:'

1. YA device of the character described comprising a frame, a metallic rim secured in said-frame, a plate carried by said rim, said plate having an opening, an optical system carried by said plate in alignment with sad member comprising a metallic plate, said plate having a smaller area than the area enclosed-by said member, said plate having an opening in which a telescope unit is secured and a lens carried by said member adjacent to said plate.

6. A pair of telescopc goggles comprising two eye units connected by a bridge, a goggle lens carried by each of said units, a plate mounted in each of said units adjacent to the lens, said plates having apertures, a field glass having lens tubes, said 'tubes being detachably mounted in said apertures.
